... and the general formula Mg 0.5 [ Me 2+ Me 3+ (Te 4+ O 3 ) 3 ]·4.5H 2 O. Until recently three mineral species were known in this family, all with Me 3+ = Fe, namely zemannite, Mg 0.5 [ZnFe 3+ (TeO 3 ) 3 ]·4.5H 2 O ( Mandarino et al . 1976 ), kinichilite, Mg 0.5 [MnFe 3+ (TeO 3 ) 3 ]·4.5H 2 O ( Hori et al...

... [Mg 0.5 ZnFe 3+ (Te 4+ O 3 ) 3 ·(3+ n )H 2 O] and its three analogues represent the largest number of isostructural tellurites or tellurates found among the Te oxysalts. The other two previously defined minerals with zemannite-type structures are kinichilite (defined as the Mn 2+ analogue...

... tellurium oxysalts discovered at Moctezuma mine, Sonora, Mexico (29°48′N, 109°40′W), and remains one of the most common minerals found there ( Mandarino & Williams, 1961 ). Zemannite and the isostructural minerals kinichilite, keystoneite, and ilirneyite all have a zemannite-type structure. Aside from...

..., tomiolloite shares some similarities with the microporous tellurite zemannite ( Missen et al. 2019 ) and the isotypic minerals keystoneite ( Missen et al. 2021a ), kinichilite ( Hori et al. 1981 ; Miletich 1995 ), and ilirneyite ( Pekov et al. 2018 ). Like zemannite, tomiolloite contains isolated neso...

... mine dumps in the district, we have identified a wide variety of secondary minerals, including numerous Te oxysalts: adanite, bairdite, burckhardtite, carlfriesite, choloalite, emmonsite, eztlite, fairbankite, frankhawthorneite, jensenite, khinite, kinichilite, kuksite, leisingite, mcalpineite...
